Nice idea. I think if you did it again and also let it melt just a bit more so that there are one or two long trails of water drops farther down on her breasts, it will add to the sensuality. I second bobnospum's recommendations, too.
Cool idea (pun intended). Maybe a blue dress to be in the "cool" color family and something other than a string (gold chain perhaps) would have matched the elegance of the rest of the photo.
